Chii chinonzi Molybdenum disulfide?
Molybdenum disulfide (MoS2) yakakosha lubricant yakasimba, inozivikanwa se "mambo wemafuta akasimba"
1. Molybdenum disulfide ihupfu hwakasimba hwakagadzirwa kubva kune zvakasikwa molybdenum concentrate powder mushure mekucheneswa kwemakemikari.
2. Rudzi rwechigadzirwa chacho dema uye zvishoma silvery grey, ine metallic luster, uye inonzwa inotsvedza kana ikabatwa, uye isinganyunguriki mumvura.
3. Chigadzirwa chacho chine zvakanakira kupararira kwakanaka uye kusasunga. Inogona kuwedzerwa kune zvakasiyana-siyana magirisi kuti iite isingabatanidzi colloidal state, kuwedzera lubricity uye kunyanya kudzvinyirira kwegirisi;
4. Inokodzerawo kutonhora kwepamusoro, kukwirira kwepamusoro, kukurumidza kukurumidza uye kukwirira kwemagetsi ekushanda mamiriro ekushanda, uye inowedzera hupenyu hwebasa rezvigadzirwa;
5. Basa guru re molybdenum disulfide rinoshandiswa se friction material kudzikisa kukweshera pane tembiricha yakaderera, kuwedzera kukweshera pakupisa kwepamusoro, uye kuderedza kupera kwemoto.
Kushandiswa kwe molybdenum disulfide (MoS2)
1. Kuzora pasi petembiricha yakafara mamiriro: iyo inoshanda siyana yemafuta ekuzora uye girizi ingangoita 60 ° C kusvika 350 ° C. Molybdenum disulfide solid lubricant inogona kuiswa kuKushanda tembiricha kubva pa270 ° C kusvika 1000 ° C.
2. Kuzora pasi pemitoro inorema: kazhinji, firimu remafuta remafuta ekuzora uye girizi rinongotakura mutoro mudiki. Kana mutoro ukangodarika kukosha kwaunokwanisa kutakura, firimu remafuta rinotsemuka uye nzvimbo yekukwenya inoruma. Avhareji mutoro uyo yakasimba lubricating firimu inogona kutakura ndeye 108Pa.
3. Lubrication pasi pemamiriro ekudzivirira: pasi pemamiriro ekudzivirira akakwirira, evaporation yemafuta ekuzora uye girizi yakakura, iyo iri nyore kukuvadza nzvimbo yevacuum uye inokanganisa kushanda kwekushanda kwezvimwe zvikamu. Molybdenum disulfide solid lubricating material inowanzo shandiswa pakuzora.
4. Kuzora pasi pemamiriro emwaranzi: Pasi pemamiriro emwaranzi, mafuta erubricant akajairika anozoita polymeri kana kuora uye kurasikirwa neawo ekuzora. Mafuta ekuzora ane simba rekudzivirira nemwaranzi.
5. Kuzora kwenzvimbo inotsvedza inotsvedza: Semuyenzaniso, kukwesha kwenzvimbo inotsvedza inotsvedza, senge bhurashi remagetsi remagetsi mota, conductive slider, solar collector ring pane artificial satellite inoshanda muvacuum uye inotsvedza yemagetsi kusangana, inogona kuzorwa nezvinhu zvinoumbwa. yecarbon graphite kana simbi.
6. Mamiriro ezvinhu akashata kwazvo ezvakatipoteredza mamiriro: Mumamiriro akanyanya ezvakatipoteredza, akadai semichina yekufambisa, michini yeinjiniya, metallurgical uye iron uye simbi indasitiri masangano, migodhi yemichina uye zvimwe zvikamu zvinotapurirana zvinoshanda muguruva, sediment, tembiricha yakakwira uye hunyoro uye humwe hutsinye hwakatipoteredza. mamiriro ezvinhu, molybdenum disulfide yakasimba lubricant inogona kushandiswa pakuzora.
6. Mhoteredzo inoparadza: Semuyenzaniso, zvikamu zvinotapurirana zvemichina yemugungwa nemichina yemakemikari zvinoshanda mumvura (steam), mvura yegungwa, asidhi, alkali, munyu uye zvimwe zvinosvibisa zvinosvibisa, uye zvinofanirwa kupinda madhigirii akasiyana ekuora kwemakemikari. Molybdenum disulfide yakasimba lubrication inogona kushandiswa kuparadzira zvikamu zvinoshanda mumamiriro ezvinhu aya.
7. Nzvimbo dzine mamiriro ezvakatipoteredza akachena kwazvo: zvikamu zvekutumira mumichina yakadai semagetsi, machira, zvokudya, mishonga, kugadzira mapepa, kudhinda, nezvimwewo zvinoda kudzivisa kusvibiswa, uye MoS2 yakasimba lubricant inogona kushandiswa pakuzora.
8. Mamiriro ezvinhu pasina kugadzirisa: zvimwe zvikamu zvekutumira hazvidi kugadziriswa, uye zvimwe zvikamu zvekutumira zvinoda kuderedza nguva yekugadzirisa kuitira kuchengetedza mari. Muzviitiko izvi, kushandiswa kweMoS2 solid lubricant kune musoro, kuri nyore uye kunogona kuchengetedza mari.
Molybdenum disulfide maitiro
Kuumbwa kweMoS2: S=Mo=S
MoS2 density: 4.5 – 4.8 g/cm ³
MoS2 CAS Nha.: 1317 -33-5
MoS2 Mohs kuoma: 1-1.5
